Mark Vedder:

The [largefile extension](https://www.mercurial-scm.org/wiki/LargefilesExtension) stores large files in a separate store and places SHA-1 hash "stand-in" files in a `.hglf` directory. The current  "Download as zip" functionality includes the `.hglf` directory with the stand-in hash files. We'd like to see an option in the UI next to "download as zip" button to "Include largefiles". Selecting this option would have Kallithea resolve the actual large files and include them in the zip file rather than the stand-in hash files.
